RIM.

Appuauon and 'February 5, was serial no. enorme.

To uZZ 'whom 'it "may concern:

` Be it ltnown that I. Hoces, a citizen oit the United Stat-es. residingat Tulsa, in the county Act Tulsa and State otOlrla h'oma, have inventednew and useful limproveinents in Rims. 'of 'which the following is aspecification. y i

This invention relates to meanstor iastening 'a vtire lrim to a wheel.the general"obA ject oit' the invention beingto provide means wherebythe rim can be removed 'from the wheel without entirely removing thenuts from the bolts which tasten the rim to the wheel so that the rimcan be easily and quiclily removed from the wheel or replaced thereon.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out iu the append ed claim.

ln describing` my invention in detaila reference will be had totheaccon'ipanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a side view ot a wheel supplied with my invention.v

Figure 2 is a section on line 2 2 ot Fig ure 1.

Figure 3 is a fragmentary sectional view showing the slot for the valvestem.

Figure 4 is a view of the toothed portion of the rim.

Figure 5 is a similar view ot the toothed portion of the telly.

Figure G shows one ot the lugs in elevation and end view.

Figure Y shows a tool used for rotating the rim onl the wheel.

Figure 8 is an elevation showing the invention applied to a disc wheel.

Figure 9 is a` section on line 9-9 ot Figure 8.

Figure 10 is a section on line 10-10 of Figure 8 with the tire removed.

Figurevll is a view .Ot a portion ot the attaching ring.

Figure 12 shows a tool for rotating this ring.

Figure 13 is a view of the brace used tor turning the nuts and thetools.

Referring to the first form ot' the invention, the lugs 1 are welded orotherwise connected with the rim 2 whichsupports the tire A. Each ofthese lugshas an "open end# ed slot 3 therein for engaging the bolt 4:which passes through the channel-shaped telly 5 ci the wheel. B.ylilac-hing 4is also provided with a recess fG for receiving the nut 7of the'bolt i and each lug is provided with a` 1wedge-shaped projection8 which enthe outerflffinge otthetelly 5.

From the foregoing it will" be seen that it is simply necessary toloosen the nuts and then give the rim 2 a slight rotary movement tocause the lugs to pass from under 'the nuts and to leave the bolts sothat the rim can be removed from the wheel. By means of the recesses 6in the lugs the parts are tirinly held against movement when the nutsare screwed home and said nuts must be moved a sutiicient distance toclear the raised portions ot the lugs adjacent themouth of the slot ineach hueY before the rim' can be rotated. In order to give the rim thisrotary movement I form ratchet teeth 9 in a portion of the rim andsimilar teeth 10 in a portion et the telly for receiving the wings 11 ota tool 19, which has 'its head 13 formed to enter the socket oi' thebrace 14 which is used to turn the nuts on the bolts e. Thus by placingthe tool in engagement with the teeth 9 and 10 and then rota-ting it bythe brace the rim is rotated on the wheel so as to place the lugs intoengagement with the bolts or to remove them out of engagement with thebolts. ln order to permit this movement of the rim on the wheel a slot15 is made in the telly to receive the valve stem of the tire so thatsaid stem will not intertere with the rotary movement of the rim.

Where the invention is to be'used on a disc wheel the attaching ring Cfor holding the rim 2 to the disc wheel B is formed with key-hole shapedslots 16 for receiving.

the bolts el and the small ends of these slots are provided withrecesses 16 for receiving the nuts 7. The large ends of thegslots` areof suiiicient diameter to permit the nuts to pass through them so thatthe rim can be put in place or removed from the wheel. A slot 17 isformed in the ring with one edge provided with the ratchet teeth 18 anda hole 19 is formed ina part ot the wheel to receive a projection 20 ona tool 21 which is formed with the wings 22 for engaging the teeth 18.This tool 21 is adapted to be actuated by a brace similar to that shownin Fi ure 13.

Thus it will be seen that the ring is partially rotated to place thebolts in engagement With the large or small ends of the slots and whenthe bolts engage theksmall ends of thel slots and the nutsare screwedhome in the recesses 16 the ring is firmly lockedto the Wheel and thuswill hold the rim and tire in position thereon.

My invention provides meansy whereby a tire and its rim can be easilyand quickly removed from a Wheel or placed thereon as it is notnecessary to entirely remove the nuts from the bolts as these nuts'needbut be loosened sufficiently to raise them above the recesses. The tooland the racks provide means for facilitating the rotary movement of theparts.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

l desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts,providedthaty such changes fall within the scope of the appended claim.

What I claim Visz- In combination with a Wheel and its demountable rim,bolts passing through the felly of the Wheel with their screw threadedportions projecting from the outer face of the felly, lugs connectedwith the rim and extending inwardly and each lug having a slot thereinopening out through one side thereof and each lug having a recess in itsouter face which has the inner end Of the slot in its bottom 'and nutsvrengaging the threaded ends of the bolts, each nuthaving a flat underface for engaging a recess in the lug and said slots permitting removalof the rim upon a relative rotationthereof When the nuts have beenremoved sufciently to clear said recesses.

In testimony whereof I aiix my signature.

CHARLES L. HoBBs.
